There are some scenarios in which developers or administrators need to compare Reports within or across Projects to ensure the integrity of both data and the underlying SQL to generate it. Examples of these include once objects are migrated from one Project to another, if Project Duplication occurs and some changes are performed to objects, or if a source database (for example, a data warehouse) has been updated or upgraded. MicroStrategy Integrity Manager is a tool that helps to compare the SQL generated by a Report and the data returned as a result of its execution side by side.
